Bend Allowance Calculator

The bend allowance describes the length of the neutral axis between the bend lines, or in other words, the arc length of the bend.

The bend allowance added to the flange lengths is equal to the total flat length of the part.

The bend deduction, sometimes called the bend compensation, describes how much the outside of the sheet has been stretched.

Therefore, the bend deduction equals the difference between the mold line lengths and the total flat length.

The mold line lengths are the distances measured to the outside mold line and are equal to the flange lengths plus the setback.

We also have Air Bending Force, Deep Drawing Force, Spring back and Wipe Bending Force Calculators.

Select your K-Factor, then enter your Thickness, Radius and Angle values and then which units you require and your results will appear, results will update as values are changed.
